RSV-induced tumors in chickens: resistance to pulsed current in terminal and non-terminal types.

Terminal Rous sarcoma virus-induced tumors in chickens had lower resistance to a pulsed current than non-terminal tumors or healthy tissues. This finding suggests the existence of some basic physiological difference between terminal and non-terminal tumors. The terminal tumors may have a higher concentration of mobile ions than either non-terminal types or healthy tissue.
